NR 283 Exam 3 Concept Review / NR283 Pathophysiology Exam 3 Study Guide (Latest):
Pathophysiology: Chamberlain
Hematology
RBC-function- Erythrocytes (or RBC’s) are the most abundant cell type in the body
Its primary job is tissue oxygenation
The cell has 2 unique properties:
o A biconcave shape which makes it optimal for gas transport
o The capacity to be reversible deformed. The cells can change shape to make it
through all the different size vessels in the body
Erythrocytes have a lifespan of 120 days
Hemoglobin is the oxygen carrying protein of the erythrocyte that gives RBC’s their
color
Each erythrocyte has over 300 hemoglobin molecules; 1 HGB can carry 4 oxygen
molecules
Erythropoiesis is the creation of erythrocytes from the bone marrow
Erythropoietin-produced, what does it do- Erythropoietin is the hormone that stimulates the
production of erythrocytes.
o It is produced by the kidneys
